Yupz........you are right.
I guess I was not very attentive :-[
Anyway the higher the temperature the more particles will be having activation energy.
The number of particles is represented as the area after activation energy. In this case area is greater for the lower peak.
Hence at lower temperatures, the lower peak should be used. ;)

16,
18,
24, (Why A and not C)
25, (I know it either A or D but cant choose which one)
30, (I dont see how this would be hydrolised)
31,
34,
36, (what does disproportionation mean)
39, (How are hydrocarbons oxidised in a convertor)
